Video-Based Learning Versus Traditional Method For Preclinical Course of Complete Denture Fabrication

Statement of the problem: advances in computer science and technology allow the instructors to use instructional multimedia programs to enhance the process of learning for dental students. purpose: the purpose of this study was to determine the effect of a new educa-tional modality by using videotapes on the performance of dental students in preclinical course of complete denture fabrication.materials and method: this quasi-experimental study was performed on 54 junior dental students in shahid beheshti university of medical sciences (sbmu). twenty-five and 29 students were evaluated in two consecutive semesters as controls and cases, respectively for the same course. the two groups were matched in terms of knowledge about complete denture fabrication and basic dental skills using a written test and a practical exam, respectively. after the intervention, performance and clinical skills of students were assessed in 8 steps. eventually, a post-test was carried out to find changes in knowledge and skills of students in this regard.results: in the two groups with the same baseline level of knowledge and skills, independent t-test showed that students in the test group had a significantly superior performance in primary impression taking (p= 0.001) and primary cast fabrication (p= 0.001). in terms of anterior teeth set up, students in the control group had a significantly better performance (p= 0.001). conclusion: instructional videotapes can aid in teaching fabrication of complete denture and are as effective as the traditional teaching system.
